?" (Ali to from it may concern:

Be it known that I, JOHN I. AsNnR, a citizen of the United States ofAmerica, residing at Baltimore, State of ldaryland, have inventedcertain new and useful improvements in Finger-Guards for Sewing-Machines, 01 which the following is a specification.

This invention relates to sewing machines and has special reference to afinger guard for the presser foot of a sewing machine.

One important object of the invention is to provide an improved andsimplified fin ger guard which can be applied to the presser foot ofpractically any sewing machine and will act to prevent the operatorsfinger from getting beneath the needle.

A second important object of the invention is to provide a device ofthis description which can be made from a blank of sheet metal.

lVith the above and other objects in view, the invention consists ingeneral of certain novel details of construction and arrangements ofparts hereinafter fully described, illustrated in the accompanyingdrawings, and specifically claimed.

In the accompanying drawings, like characters of reference indicate likeparts in the several views, and

Figure 1 is a perspective view of a portion ofa sewing machine showingone form of my invention applied thereto.

2 is side elevation of the presser foot and associated parts showing theguard in section applied to the presser foot.

Fig. 3 is a plan view of the part shown in Fig. 2.

Fig. 1- is a perspective view of the guard removed.

Fig. 5 is a detail showing the blank from which the guard is formed.

Fig. 6 is a view similar to Fig. 1 but showing a modified form of guard.

Fig. 7 is a view similar to Fig. 3 of the modified form.

Fig. 8 is a perspective view of the modified form removed from thepresser foot.

Fig. 9 is a view of the blank from which the modified form is made.

In the drawings illustrating the invention there is shown a presser bar10, presser foot 11, needle bar 12 and needle 13 all of ordinary andwell known form such as are used on many sewing machines.

The presser foot is provided with the I usual upturned end 14 and, asiscommon in machines, this upturned end is somewhat longer than the otherside of the presser foot and the needle passes between the two sides asshown.

The guard itself is formed from a single blank of sheet metal bypreference. Each blank consists of a main rectangular body portion 15divided by transverse fold line 16 so that this portion of the body maybe folded at these lines to form a cuff as indicated at 17, the underpart of which is beveled at 17 which can be slipped over the upturnedend 14 of the presser foot. The upper side of'this cuff is provided witha screw thread opening 18 wherein fits a screw 19 serving to lock thecuff in position on the presser foot. 9 there projects from the body 15a'lateral portion 20 extended at one end as at 21, the latter portionbeing defined from the body by a fold line 22, and, in the completedarticle, being bent up on this fold line 22 to constitute a guard orbarrier 23. This construction is also followed in the form shown in Fig.5 but, in addition, an extension is formed on the portion 20 which isdivided therefrom by a fold line 24, the extension being curved as shownat 25 in Fig. 5, and when bent on the fold line in the completed articleforming a side guard 26 to protect the finger from slipping laterallybeneath the needle.

In use the cuff 17 is simply slipped over the end of the presser footand the screw 19 screweddown. The device will then be in position sothat in each form the finger of the operator will be prevented fromslipping beneath the needle from the front of the presser foot by theguard 23 and, in the form shown in Figs. 1 to 5, the finger will beprevented from slipping laterally by the guard 26.

There has thus been provided a simple and efficient device of the kinddescribed and for the purpose specified.

Having thus described the invention, what is claimed as new, is:

1. A finger guard for sewing machine presser feet comprising a cufiadapted to fit In the form shown in Fig.-

' over the toe of a presser foot, a guard plate 7 means to i'eleasablyhold the guard on thepresser foot.

2. A finger guard for sewing machine presser feet constructed of aslngle plece of sheet metal having a body portion adapted to be foldedto form a cuff, and a portion projecting laterally therefrom adapted tobe folded to be bent upward to form a guard, in combination with meansto 'releasably hold the cuff on a presser foot.

In testimony whereof I aflix my signature.
